+         Modern CIFS servers including Samba and most Windows versions
+         (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
+         security mechanisms. These hash the password more securely
+         than the mechanisms used in the older LANMAN version of the
+          SMB protocol needed to establish sessions with old SMB servers.
+
+         Enabling this option allows the cifs module to mount to older
+         LANMAN based servers such as OS/2 and Windows 95, but such
+         mounts may be less secure than mounts using NTLM or more recent
+         security mechanisms if you are on a public network.  Unless you

+         network) you probably want to say N.  Even if this support
+         is enabled in the kernel build, they will not be used

+         can be set to required (or optional) either in
+         /proc/fs/cifs (see fs/cifs/README for more detail) or via an
+         option on the mount command. This support is disabled by
